Specification of Letters Patent.

Patented June '23, 190s.

Application filed March 14, 1904. Serial No. 19B,168.

To alll'whom it may concern: Be it known that we, ARTHUR TREvoR DAWSON, lieutenant of the Royal Navy and I vdirector and superintendent of ordnance works, and GEORGE THOMAS BUCKHAM, engineer, both subjects of the King of Great Britain, residing at 32Victoria street, Westminster, the county of London, England, have invenzed certain new and useful Devices for Sighting and Training Quick-Firing Ordnance, of which the following is a specification.

Our invention relates to the sighting and working of quick firing ordnance, and is for the purpose of effecting the same in a more eflic1ent, reliable and convenient manner than heretofore. We so combine the sighting, elevating and 'training gear of the mounting, that the diHerent operations may be independently performed b three men situated upon platforms carrie from Veither or both sldes of the mounting.

According to our present invention we arrange a complete set of sighting elevating and training gear on each side of the gun, with` means for enabling the elevating gear on one side to be thrown out of action when the elevating gear on the other side is to be worked.

Our present invention also has reference to the graduated drums or disks for indicating range and defiection, as will ,be hereinafter described.

In order that our said invention may be clearly understood and readily carried into effect we will describe the same more fully with reference to the accompanying drawings l Vin which Figure 1 is a' left hand side elevation.

Fig. 2 a right hand side elevation, and Fig. 3 a plan of a pedestal mounting for va quick firing gun with our improvements ap lied thereto. Fig.'4 is a sectional plan s owi ing so much of the parts as is necessary to explain the gearing used for trainingthe gun. Fig. 5 1s a front elevation and Fig. 6 a vertical section of the means employedfor i enabling the elevating gear on one side of the rriountingto be thrown out of action when the elevating gear on'the other side 1s tobe worked. Figs. 7 and 8 are detail transverse sections taken approximate-1y .on the lines- A is the gun a apted to -recoil in the cradle A which is trunnioned in the mounting B. l

C C yare the hand wheels of the sighting gear, D D the hand wheels of the gun elevating gear, and E EX the hand wheels of the training gear, the gear being in each case duplicated i. e. arranged in two sets on 0pposite sides of the mounting, each set being worked by three men or numbers standing on the platforms B B2.

D2 D2X are shoulder `pieces against one of which the man No. 2 controlling the gun elevating gear can lean and steady' himself while looking through the sight c or cx. D3 D3X are pistol grips or firing levers for enabling said man No. 2 to fire the gun.

The two sights c cx are coupled together by means of transverse connecting rods c9 c10 so that the said sights can be simultaneously actuated from either side of the mounting, for range setting and deflection.

The rod c9 is bent and provided near -its middle with a crank C10 carried by a bracket AX. The ends of said rod are adjustably of which the elevating gear of one sight is worked from the other. the said cranks es is provided with a worm c11 the s aft c13 that carries the inion c14 for actuating the elevating rack ar 015 of the sight. On the axle c1E that carries the crank c8 is a bevel pinion 027 which gears with a bevel pinion 018 mounted on the axle that carries the hand'wheel C-or CX.. By revolv` ing one or other of said hand wheels therefore,

vthe two sights `can be simultaneously moved for changing their elevation.

The said sights are also connectedv by .means of the said cross bar c19 by means of which they can by actuatcoupled to cranks or crank disks c8 by means The axle of each of that ears with a worin-wheel c12 mounted on v impediment.

We do not herein claim either e sight for ordnance comprising two sighting members d ioosed one on esen side of the gun, means nilteneonsly elevating end depressing i members, and. means for simultaneously seid members leterelly; or, a sight oor risinf two sighting memoser :it em;AL side of tile gud, end
